Fate/Stay

A robotic arm grips a glowing sword, which is then drawn from its sheath by a young woman with blonde hair who shouts the name "Excalibur!" as golden light erupts around her. The sword is swung forward, creating a massive explosion of golden energy that travels through the air and impacts a surface, sending a shockwave and debris flying. The scene takes place against a backdrop of a bright, glowing sky and a dark, stormy sky.
